CHARLES FRANKISBQOF CHICAGO, ILLINOIS 5 Letters Patent No. 111,189, dated January 24,1871; antedated January 14, 1871.

|MPRovEwIEN-r` IN wA'ri-:R-cLosErs.

The vSchedule referred to in 'these Letters' Patentand making part of the same.

To all whoit 'it may con-cern:

VBe it known that I, CHARLES -Fnanxrsm of Ohicago, inthe county of Cook and State of Illinois,

the objections to the common watercloset are obvi-` -ated; and

It consists in a hemispherical hopper formed of two quarters of ahollow sphere, arranged and operating on the end of a vertical hollow cylinder, in the man-y 'ner hereinafter more fully described. v

In the accompanying drawing- Figure 1 represents a vertical section, showing the front of the apparatus and the method of-hinging the two quarter-spheres to the top of the cylinder.

Figure 2 is a central vertical sectionv in the other direction. l

Similar' letters of reference indicate corresponding parts.v I

A is the seat-frame or closet.

B is the seat, which is hinged tothe back of the closet, as seen at (l, with the ordinary orifice through it, as indicated in the drawing. v I

D represents an 'upright hollow cylinder, which is snpported'by the shelf E, through which it passes. F I? are spiral br other springs, lwhich rest on the shelf E and bear'upward against the under side vof the seat, near its front edge, with a constant pressure, which serves to force the seat up to the stop-cleats G G, when it is not in use.

H H represent quarter sections of a hollowsphere, around the edges of which there is a light flange, as indicated in the drawing.

Each section is provided with a pivot at one Vend or angle, and a crank at the other.

'Ihese pivots-or jonrnads and cranks are connected at the extreme angles of the sections, and rest on the4 top of the cylinder in close contact, so that the edges of the sections can come in contact with-cach. other, and form a close joint when 'turnedin either direction.

I represents the cranks; and

J, the pivot-journals.

K is a bracket, which is attached to the seat..

Lis a double-journal'box for the cranks, which is attached tothe cylinder.

'lhewrists of the cranks I passV through slot-holes lm, in the bracket K:

The vertical dotted lines N, as seen in' g. 1, represent the iianged edges of the'sections, the two sections in a position seen from a hemisphere, with its convex side'just beneath the scat. It Will be seenthat the cranks I stand at an-angle of about forty-five degrees with the perpendicular joint N. Now if a weight is placed on the seat suff ciently heavy to force it down, the crankswill'be carried down to the `position seen in dotted lines, and

the sections will also be carried so as to form a hemisphere reversed, or'with the convex'side down, as

indicated indotted lines.

lVhen the weight is removed irom the seat, the

springs recoil and throw the seat] up again, and the sections .into the position seen in the drawing.

It will be seen from this, that if the person is tol v u se the seat, the moment he sits down or'hears upon it, the sections separate at the top and close togetherV at the bottom.

The flanges on the edges of the sections form,'with the top of thecylinder, a tight joint, so -that all noxions gases'and poisonous exhalations are eiectnally excluded, as well as draughts of-air, so disagreeable and dangerous to delicate persons in cold weather.

There are butfew situations where this arrangement will not be of the greatest advantage; in preventng'the rise ofn'cxious and'unhealthy'exhalationsl fromprvy yaults, and preventing cold draughts of air,

and stopping the splashing of water into the privy onj shipboard, and the dust and cold in railroad cars.

Having thus described my invention,

I claim as new and desire to secure by Letters Pat-V ent- In combination with a watercloset or privy-seat, the sections H H, when the v,same are arranged to operate substantially as and for the purposes herein shown and'desc'ibed.
